Pro-source 2556438365PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556438365PRO is a push-to-connect tube fitting designed for quick, tool-free connections between tubing and universal-threaded ports. Constructed from nickel-plated brass, it accepts 3/8 inch OD tubing and features a 3/8 inch universal thread connection. Rated to 250 psi, this fitting is built for compressed air and water service in light industrial, HVAC, and plumbing applications. A Buna-N O-ring provides a reliable seal at the threaded interface. Installation requires no ferrules, compression sleeves, or thread sealant on the push-to-connect side, reducing assembly time in the field.

This fitting is suited for residential and light commercial systems where compressed air lines or water supply connections require a fast, repeatable tube connection at a threaded port. Typical applications include pneumatic control circuits, equipment supply lines, and plumbing rough-in work where 3/8 inch OD tubing is routed to a universal-threaded fitting body. Sold in a package quantity of 5, making it practical for multi-connection jobs or stocking a service van.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion for 3/8 inch OD tubing

Compatibility

Designed for use with compressed air and water systems using 3/8 inch OD tubing and universal-threaded port connections in light industrial, HVAC, and plumbing applications.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or industrial maintenance personnel. Before installation, depressurize and isolate the line completely. Ensure tubing is cut cleanly and squarely, with no burrs, to achieve a proper push-to-connect seal. Verify thread compatibility and hand-tighten the threaded end before applying a final snug turn with an appropriate wrench to avoid over-torquing the brass body.
